What 245/55R18 tires means
The size code breaks down into precise measurements. The 245 is the section width in millimeters (about 9.65 inches across the tread). The 55 is the aspect ratio, meaning the sidewall height equals 55% of the section width — roughly 134.8 mm, or 5.31 inches tall. The R indicates radial construction, and the 18 is the wheel diameter in inches that the tire mounts to.
Put together, a 245/55R18 tire has an overall diameter of about 28.61 inches and turns roughly 705 revolutions per mile. Those figures matter because they determine speedometer and odometer accuracy, wheel-well clearance, and ride feel. Staying close to your vehicle's original diameter keeps your speedometer honest and avoids rubbing, while the 5.31-inch sidewall offers a balance of comfort and steering response.
Vehicles & uses
This is a common size for larger sedans and crossover/SUV applications, according to industry listings that group 245/55R18 among passenger and SUV fitments. It suits vehicles that value a taller, cushioning sidewall over an ultra-low-profile look. Because exact fitment depends on your specific year, make, model, and trim, confirm the size stamped on your door placard or current tires before ordering.

How to choose
Season
Match the tire to your climate. Summer tires deliver the sharpest dry and wet grip in warm conditions, all-season tires balance year-round usability, and winter tires are engineered for snow, ice, and cold-temperature traction. Several 245/55R18 options here span each category.
Treadwear & UTQG
The UTQG rating printed on the sidewall reports treadwear, traction, and temperature grades. A higher treadwear number generally signals longer expected tread life, while traction and temperature grades indicate grip and heat resistance. Compare these ratings tire-to-tire rather than across categories.
Load index & speed rating
The two-part service description (for example, 103V, 103W, or 103Y) states the maximum load each tire can carry and its speed capability. Choose a load index that meets or exceeds your vehicle's requirement, and a speed rating appropriate for your driving.
Warranty
Many all-season and touring tires include a mileage treadwear warranty. Review each product's terms so you know what coverage comes with your purchase.
